Drupal content Management System
Drupal is an extremely powerful system that rewards the users who climb the fairly steep learning curve. The Adodis for Drupal lowers the learning curve a little by giving you a Drupal installation that’s ready to run in just minutes allowing you to focus on using Drupal rather than getting it installed.
Using an existing CMS means you don't have to rebuild the wheel when it comes to the basic functionality like logging in, security, creating and editing content. All these are in place, and if they don't exactly meet the requirements, they can be extended in a way that enables one to build on the existing code.
